rier fastto a `rock-shaft on whicnarealsoast thelay-swords'that carry the lay erba-tten. The picking `mechanism lusually includes, with the picker-stick. some form of buffer with which the stick at its upper end portion contacts and, as a separate device, some iiexible longitudinally extensible elastic medium for effecting retraction of the stick, as a spring extending under its pivot and attached at its ends to the stick and the carrier. My object is to simplify the picking mechanism in respect to so much thereof as affords the buffer and provides for retraction of the stick. To that end I contemplate combining with the stick and carrier what is in effect a unitary assembly readily attachable to any standard picker-stick carrier and of such construction as to withstand the wear and tear imposed thereon much longer than either of the men- ;ioned devices.

The invention is herein shown applied to a ox-loom but it may be applied, as will be aparentl to a plain loom.

In the drawing,

Fig. 1 shows the carrier and my device in plan .nd the picker-stick in section;

Fig. 2 is a plan of said device on a larger scale;

Fig. 3 is a front elevation of said device, with part of the carrier appearing in broken lines; `nd

Fig. 4 shows the carrier, picker-stick and said evice in front elevation.

On the horizontal rock-shaft I, journaled in he frame a, is made fast, as by set-screws 2, the sual carrier 3 in whose terminal 3a the pickertick 4 is pivoted to move in an upright plane xtending lengthwise of the rock-shaft. Said irrier being here adapted for a box-loom havlg shiitable boxes, it is formed with a rearward and as seen in plan and as usual and, upstandlg from such bend, with a guiding portion 3b r guiding the box-rod 5. The pivot for the .cker-stick is formed by a pin or bolt 6 which znetrates the terminal 3a and is formed with collar 6a and has a nut 'l for clamping it to le carrier, 8 being the usual Cotter-pin to retain .e picker-stick on the bolt.

According to this invention means is provided r checking the shuttle-impelling movement of ld thereupon retracting the picker-stick (or ick) 4 as follows:

A bracket is made fast to the carrier and in e present instance includes the following parts:

is an L-shaped part or angle-iron to one arm which is rigidly fixed, as by a bolt or rivet IB w, aiplazted I which isipernerrdicuiarftofandmrojects .from .the .cornmoniplane of both m'msif iaxarta'l:mortsy @fand FI I :may tof Apousse existes :a unit, or amande-shaped'member havingvextending from one arm thereof and from said plane a projection, as Ila (Fig. 4). Such projection and hence the bracket is here clamped to the carrier by the bolt 6 and nut l so that the other arm of the bracket extends forwardly, or through the plane of movement and lateral of the stick. Projecting from that side of the latter arm which adjoins the stick is a pair of spaced guide-pins I 2, preferably fixed to said arm in any way, as by being welded thereto.

On the pins of the thus-formed bracket and arranged in the path of movement of the pickerstick is an elastic buffer means formed as follows: A U-shaped buffer I3, formed of some tough, preferably brous material, as raw-hide, is slidable on the pins I2, its extremities projecting toward said arm of the bracket and penetrated by the pins. Between its extremities the buffer has a stud I3a projecting toward said arm. Bearing against that face of said arm which adjolns the buffer is a yielding somewhat elastic pad I4, as of leather, penetrated by the pins. And between the pad and buiTer is a helical spring I5 into which stud I3a projects and which normally tends to maintain the buffer at the limit provided by the heads of the pins I2.

In this example the device comprising the bracket and the elastic stick-control or buffer means is so related to the terminal 3a of the carrier that said means is at an elevation below that of the picker-stick pivot whereby the part of the stick below such pivot will at its outer side contact said means, which is here outward of the stick; but, obviously, the formation of the carrier being such that said device could be accommodated, the latter could be positioned, in inverted state, at an elevation above that of the pivot, in which case the stick would contact said means above the pivot and at its own inner side.

In any event, it will be understood that the device is so constructed and should be so arranged that when the picker-stick is made to undergo the shuttle-impelling movement (or clockwise in Fig. 4) the parts I3-I5 of said yielding stickcontrol means substantially immediately oppose such movement.

More specically, on the shuttle-impelling stroke of the stick its movement is at rst yieldlngly opposed by said parts I 3 I5 of said means but nally it is more positively but still yieldingly opposed by the parts IB-II. Thereupon the parts l8| l again come into effect to retract the stick.

The construction is not only such that the checking and retracting functions are performed by what is a unitary assembly readily attachable to any standard loom but the arrangement and disposition of the parts of said assembly are such that they most efficiently coact with the pieker-v stick and well withstand the strains and stresses imposed on them.

It is noted that the picker-stick pivoting bolt 6 itself provides the means for securing the bracket to the carrier. Further, that that surface of the arm of the bracket beyond which pro-V jection lla extends provides a ledge 9a contactlil A and in a horizontal plane close to but removed Having thus fully described my invention, what I claim is:

l. In combination, with the pickerstick carrier of a loom and a picker-stick pivoted therein to move in an upright plane, means to check the shuttle-impelling movement of and thereupon retract the picker-stick comprising a bracket L-shaped in plan and having one arm thereof afilxed to the carrier and the other projecting, laterally of the picker-stick, through said plane from the horizontal plane of the picker-stick pivot, and elastic buffer means supported by the bracket between the latter arm and the pickerl5 stick.

ing the under edge of the carrier terminal 3a',

whereby to prevent the bracket from shiftingv around the bolt B.

To remove for repairs or replacement any oi the parts I3, i4 and I5 it is only necessary to dismount the picker-stick, which otherwise 0bstructs removal o! the buffer from pins I2.

2. In combination, with the picker-stick carrier oi a loom having a projecting pivot-forming clamping' device and with a picker-stick pivoted on said device, a bracket penetrated and clamped to the carrier by said device, and elastic means, carried by the bracket, to check the shuttleimpelling movement of and thereupon retract the picker-stick.
